Filed: 2020-08-07
Abstract: To provide a device for detecting misfire of an internal combustion engine which is configured to be able to calculate torsion velocity components in a plurality of frequency bands with the same processing.SOLUTION: A CPU substitutes a difference between a crank side velocity ωe as the rotation velocity of a crank shaft and a rear stage side velocity ωout as the velocity of a damper on the opposite side to the crank shaft into a differential velocity ωdamp (S46). The CPU calculates torsional angle θdamp by using the integration processing for the differential velocity ωdamp (S48). Based on the integration processing for the torsional angle θdamp multiplied by an elastic coefficient K, the CPU also calculates a torsion velocity component ωr as the velocity component of the crank shaft resulting from the torsion of the damper, and based on the calculated ωr, also calculates a time T30 as a variable showing the velocity of the crank shaft to be used for determining misfire (S54). The CPU subtracts, from the output value of the integration processing, a value obtained by applying finite response type low-pass filter processing to the output value.SELECTED DRAWING: Figure 3
